Audi Q4 e-tron active lane assist
Audi Q4 e-tron is equipped with Active lane assist. Operating at speeds from 65 km/h (40.4 mph), Audi active lane assist helps the driver keep the vehicle in the driving lane.
A camera detects lane lines and the track that the car is following between them. In this process, the camera can distinguish between yellow lines in construction zones and standard white markings. If the car approaches a line without the turn signal being activated, the system helps the driver to steer back into the lane by means of gentle but noticeable interventions in the electromechanical power steering. In the MMI system, the driver sets how early the control intervention should occur. In the case of an early steering intervention point, the system guides the driver towards the middle of the lane by gentle, centering steering interventions. With a late steering intervention point, Audi active lane assist does not intervene until shortly before the detected lane marking might be crossed; then it gives a corrective steering intervention in the proper direction. In addition, the driver may choose to be warned by a vibration of the steering wheel when crossing detected lane markings.
The Active Lane Assist can be disabled on the button at the end of the direction handle. It is not possible to permanent disable it.
This is because under new EU vehicle safety rules, all new car and van models must be equipped with emergency lane keeping systems (ELKS) from July 2022, and existing models from July 2024 EU requires.
Active lane assist is standard equipment.
